BOX-COVER DETAcHEn.

SPECIFICATION forming part of Letters Patent No. 789,509, dated May 9,1905.

Application filed September 20, 1904. Serial No. 225,285.

To all whom, it may concern.-

Be it known that I, EDWARD S. SAVAGE, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented a certain new and useful Improvement in Box-CoverDetachers, of which the following is a specification.

The present invention relates to means for separating a box and itscover, the object of the invention being to provide means permanentlyattached to one or the other of said box and cover parts and actingagainst the other for forcing them asunder, so that the cover may bewholly removed if merely held in place by friction or may be swung asideif pivotally connected with the box and held in place by friction whenclosed down.

To the end thereof the invention consists of features of constructionand combinations of devices hereinafter described, and more particularlypointed out in the appended. claims.

One form of the invention is illustrated in the accompanying drawings,forming part hereof, in which Figure 1 is a side elevation. Fig. 2 is aplan, and Fig. 3 is a vertical central sectional View.

In the drawings, the reference-letter a denotes the box proper, and 7)the cover therefor. The box a has a bead c therearound except where itis left fiat at (Z, where the cover moving or lifting device is pivotedto or fulc'rumed on the box. By preference the cover lifting or movingdevice consists of a cam, as an eccentric c, which is provided with oneor more arms or levers f, whereby it may be operated, and which isrotatably connected With the box at said point (Z in any suitablemanner, as by a rivet g. In the preferred form of the cam it is beveledat it, so that it will engage with the inside rather than the outside ofthe edge of the cover 7). When the cam is in the shape of an eccentric,it is conveniently formed by drawing or striking up sheet metal in theform of the frustum of a cone with the opening at the small end and theformation of arms or levers f thereon during the process of manufacture,whereby the beveled feature is retained and its advantages in removingthe cover secured. It is also preferred that the cover 7) be formed witha flare or bell 71, so that the bevel or cone /1. will tend to move thecover away from rather than to bind it more lirml y against the box a.This preferred arrangement also tends to prevent the loosening of thecam on the rivet.

By turning the eccentric either way from the position shown in Fig. 1the cover?) is forced upward at that side and is so loosened that it mayreadily be removed by hand no matter how tightly it fitted on the box.

It is preferred to have the cover-lifter attached to the box, as sucharrangement avoids the necessity of special provision of a hearing onthe box for the cover-lifter to act against, as in the said preferredarrangement the lifter may act against the edge of the cover.

The invention may be embodied otherwise than as herein shown. I do not,therefore, limit my claims to the embodiment shown in the drawings andabove described.

By the word box in the claims 1 include also a bottle or otherreceptacle on which the cover is held by friction.

V hat I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. A box, a cover therefor, and a beveled cam pivoted to one and actingagainst the other next the junction-line between said box and coverparts to cause relative motion thereof to remove the cover.

2. A box, a bell-mouthed cover therefor, and a beveled cam pivoted tothe box and. acting against the edge of the cover next to the box.

3. A box, a bell-mouthed cover therefor, and a coned eccentric pivotedon the box with its larger end thereagainst and in position to actagainst the edge of the cover.

4. A box, a bell-mouthed cover therefor, and an eccentric provided witha beveled edge and with arms integral with the eccentric for operatingit, said eccentric being pivoted to the box.

5. A box or Vessel, a cover therefor, and an eccentric pivoted on thebox or vessel and provided with means whereby it may be rotated andcaused to act against said cover to Signed at New York city, in thecounty of lift the same. New York and State of New York, this 12th 6. Abox or vessel, a cover therefor, and day of August, A. D. 1904. aneccentric pivoted on said box or vessel and EDWVARD S. SAVAGE. 5provided with arms integral therewith where- Witnesses:

by it may be caused to rotate and act against W. H. KENNEDY,

said cover to lift the same. i R. \V. BARKLEY.
